The present invention pertains to a novel window sealing construction,and the principal object ti to provide a device wherein the window isautomatically and efiectively 5 sealed against the weather at all times.

This object is accomplished essentially by constructing the partingstrip in the nature of an expansible member including two parts runninglongitudinally of the window frame.

1 At least one of these parts is slidable in the frame towards one ofthe sashes which it engages, and between the parts is provided springmeans so that said slidable part is constantly pressed against thecorresponding 15 sash.

The invention is fully disclosed by way of example in the followingdescription and in the accompanying drawing, in which- Figure 1 is avertical section of a window 20 constructed according to the inventionFig. 2 is a fragmentary front elevation of the window, partly insection;

Fig. 3 is a horizontal section thereof, showing one of the sashes raisedor lowered;

Fig. 4 is a fragmentary elevation of the parting strip, partly insection;

Fig. 5 is a transverse section thereof;

Fig. 6 is a transverse section and a fragmentary side elevation of amodified form of 30 parting strip;

Fig. 7 is a fragmentary side elevation of another modification;

Fig. 8 is a transverse section thereof; and

Fig. 9 is a transverse section of still an other modification.

Reference to these views will now be made by use of like characterswhich are employed to designate corresponding parts throughout.

In Figures 1, 2 and 3 is illustrated a window frame 1 of usualconstruction having a pair of sliding sashes 2 and 3 mounted therein.The parting strips between the sashes are of a special formation wherebythey have a sealing effect on the respective sashes. In 5 Figures 1 to 5for example the parting strip consists of a pair of channel members 4and 5, the latter of which is received within the former. It will beseen in Figure 1 that the parting strip is divided midway between itsends as at 6 in order to provide two separate and independent assembliesfor a purpose which will presently appear.

The backs of the channel members 4 and 5 are opposed to one another, andthe back of the outer channel 4 is arranged to engage the upper or lowersash as the case may be. The sides of the inner member 5 are formed withapertures 7, while the sides of the channel 4 are formed with slots 8adjacent the apertures. Springs 9 are mounted in and between the channelmembers and are seated by means of lugs 10 struck inwardly from thebacks of the channels.

Fastening nails or screws 11 driven through the apertures 7 and slots 8hold the inner channel member in a fixed position against the side ofthe window frame, while the outer channel member 4 is slidablerelatively to the inner channel by reason of the slots 8. The springs 9consequently press the channel member 4 against the sash which isengaged thereby, The two assemblies above and below the parting line 6are reversed with respect to each other, so that the slidable channel-ofthe lower assembly engages the 75 lower sash 2 while the sliding channelof the upper assembly moves in the opposite direction and engages theupper sash'3.

In the construction shown in Figure 6 there is a parting strip proper ofT-shaped cross section and designated by the numeral 15. Sealing strips16 are inserted beneath the head of the strip and in parallel relationto the stem 17. The stem is formed with a transverse bore 18 in which isreceived .a spring 19 which bears against both strips 16. This form ofthe'device therefore expands in both directions and acts on both sashesif either one is raised or lowered. A covering strip 20 is laid acrossthe base of the stem 17 and over the exposed edges of the strips 16, andthe assembly is secured tothe side of the window frame by nails orscrews 21 driven through the strip 20 and stem 17.

In the embodiment shown in Figures 7 and 8 the parting strip consists oftwo channel members 25 placed back to back and held in this relation bystuds 26. These studs are headed at. both ends and further serve to holdbow springs 27 in each channel. The mo slidably mounted therein, aparting strip be- 7 channels are secured to the side of the window frameby tacks 28 driven through one side of each. In the channels areslidably fitted sealing strips 29 engaging the free ends of the springs27 and notched at 30 to accommodate the heads of the members 28. Thisdevice also acts in both directions, by reason of the provision oftwostrips 29, in the man-v ner described in connection with'Figure 6.-In Figure 9 is illustrated a one-piece all-i metal parting striphaving abox-like.forma-- tion 31 of rectangular cross section with one endembedded in the side 32 0f thewindow frame. At the median of theopposite side the metal is bent in at 33'and drawn outaat'. 34:, induplicate fashion, so that it may be bent-as at 85 over each' of theadjacent corners of the formation 31 to bring the free ends 36 of themetal into engagement with v the sashes 37. The spring action isprovided by the band portions 34:36 which obviously act both; directionsin the same manner as the devices shown in Figures 6, 7 and 8.

Although specific embodiments ,of the invention have been illustratedand described,

it will be understood that various alterations in the'details ofconstruction may be made without departing from the scope of theinvention as indicated by the appended claims.

What I claim is 1. In a window, a, frame, a pair of sashes, slidablymounted therein,a parting strip between said sashes, saidparting stripcompris inga'pair of longitudinal, unitary, U-shaped the other andrelatively slidable, one of said members being fixed to said frame andthe other engaging said sash, lugs struck inwardly from the backs of thechannels, and coil springs disposed within said members and having theirends mounted over opposed lugs of opposed channel backs.

5. In a window a frame, a pair of, sashes slidably mounted therein, aparting strip betweensaid sashes, said parting strip comprising a,pairof. longitudinalv channel members one within the other, said strip beingsevered substantiall n idway between its ends to form two distinctparting strip assemblies, oneof the channelmembers of each assemblybeing secured to said frame and the other member being slidablerelatively thereto and engaging the adjacent sash, and spring meansdisposed between said channel members and tending to move the movable'membersagainst said sashes.
